Richardson has been suspended after testing positive for THC, a chemical found in marijuana, the United States Anti-Doping Agency said Friday.
Richardson secured her spot at this month’s Tokyo Olympics after winning the women’s 100-meter at the United States Olympic Track and Field Trials in Eugene, Oregon last month.
But her results were automatically disqualified as she tested positive for THC, and she will not be allowed to participate in her signature 100-meter race in Tokyo.
Richardson said in an interview with NBC’s “Today” show on Friday that she used marijuana after learning from a reporter that her birth mother had died.
“I just thought it would be a normal interview and then during the interview, hearing this information coming from a complete stranger, it was really a trigger, it was shocking to the nerves because it’s like who is. -you tell me that? ” said the athlete.
“From there, just blinded by the emotions, blinded by the bad news, blinded by just hiding the pain, honestly for the fact that I can’t hide, so at least in a way I ‘trying to hide my pain. “
Richardson said she wanted to take responsibility.
“I know what I did, I know what I am supposed to do, I have the right not to do it and I made this decision anyway. I am not looking for excuses or searching for ’empathy in my case,’ she said. .
The World Anti-Doping Agency and USADA qualify cannabis as a prohibited substance because it “poses a risk to the health of athletes, has the potential to improve performance and violates the spirit of the sport.”
Once the suspension is over, Richardson said in the interview, she “will be back and able to compete, and every time I get on the track, I will be ready to compete for any anti-doping agency that comes and gets what she is what they need. “
